35、their resistance to the influence of molten salts and molten metals but also showing good mechanical properties during short and long-term stressingPage 4 EN 10095:1999 BSI 07-1999 4 Classification and designation 4.1 Classification Materials covered in this European Standard are classified accordin
36、g to their structure into: ferritic steels; austenitic-ferritic steels; austenitic steels; and austenitic nickel alloys. 4.2 Designation The names and numbers of the steels (see Table 1 and 2) were formed in accordance with EN 10027-1 and EN 10027-2 respectively. NOTE Explanation on the designation
37、of nickel alloys (see Table 3). name: The preceding chemical symbols indicate the main alloy elements and the figure immediately following indicates the average content of these alloys subsequently followed by the symbol for the other added important alloy elements. material number: The structure is
